Add ss3sim paragraph to summary document; re-arrange templates

Made a couple minor edits to the other paragraphs. The main contribution is adding an ss3sim paragraph to the summary document. It's just a first draft, so please edit at will. I also re-arranged the paper folders so they rely on one main .csl and .bib file and added some references to the .bib file. Good luck with the merging if you've already been editing. :)
